They plan to buy a new house in their home town Llanelli, a villa in Gran Canaria and Liverpool fan Mr Henry wants an executive box at Anfield.

Mr Henry, a part-time bingo caller at Furnace Rugby Club, said: "At around lunchtime on Saturday I just felt lucky inside and asked Sandra to remind me to buy a couple of Lotto Extra tickets for that night's draw".

He added: "There was something on TV that reminded me of the lottery. It was a feeling I had inside that made me think I should do the Lotto Extra."

The couple picked up a cheque for £12,835,726 at a hotel in Cardiff.

The pair did not realise they had won until the day after the draw

Mr Henry, who has five grandchildren, was emotional as he described their big win.

He said when he found out they had won from a Sunday newspaper, he travelled to the Asda store where Sandra worked, but she did not believe him at first.

He said: "I whispered this is going to change your life - we've won. She said, 'won what?'"
